Hey guys, just joined. I have a few questions regarding my setup. =)
I have a little over 20L tank for my single male Betta, hiding places and fake plants (Want some real ones soon...), and wanted to know how often I should be replacing the water, and how much? This seems to vary person to person, I've been doing ~20% every 3 days. And when I do this, I usually leave the Betta in the tank and do it carefully, trying to match the temperature as best as possible, it usually doesn't fluctuate at all. Between this (Say after 3/6 water scoops) I put 3 drops of water neutralizer in to help it mix. I was also curious about the water I'm using and how much neutralizer I'm using. I'm in an area where we rely on rain water, and also using a new rain tank, so the water is chemical free and pretty pristine, but I've heard tap water is better for some reason?
Anyway, other than that, I not long ago had a Betta die randomly, he was active, eating, looking fine and stress free but died. Wondering why? Temperature was fine and stable, tank clean. I didn't have Ammonia strips at the time but I was doing water replacements, could it have had some sort of Ammonia spike?
So far the new guy is healthy and happy, but just wanted to ask the above questions to ensure he'll be cool.
Oh, he also hangs around the heater a lot when resting, is that normal? The temp is about 24*C.
